Principles of Stratigraphy and Geological Time

Pupils will apply the principles of superposition, cross-cutting relationships, and unconformities to determine relative geological ages. They will also learn about absolute dating methods.

About This Topic

Pupils will apply the principles of superposition, cross-cutting relationships, and unconformities to determine relative geological ages. They will also learn about absolute dating methods.

Key Questions

  1. How do geologists determine the relative age of rock strata?
  2. What is an unconformity?
  3. How does radiometric dating provide absolute ages?

Evolution of Life and Key Fossil Groups

This topic examines the fossilisation process and the morphology of major fossil groups such as trilobites, ammonites, and graptolites. Pupils will use fossils as zone fossils for correlation.

Mass Extinctions and Climate Change in the Geological Past

Pupils will investigate the causes and evidence of major mass extinction events, such as the K-Pg boundary. They will also explore how geological evidence records past climate changes.
